To all whom 'ift may concern.'

Be it known tlmt l, FRED MARTIN Wnrr- 1 MAN, e citizen ol the United States, and n. resident of 'l`ucson, in the county of linnn and Territory of Arizona, have invented u new and Improved ltotery Engine, of which the following is u l'ull, elettr, und exact deseription.

'1`he ohject of the invention is to provide si new sind improved rotnrviY engine. nrrnnged to permit convenient reversing und lo utilize the motive agent to the l'tlllent advantage.

The invention consists of novel tentures and parts und combinations ol' the same, which will he more fully described hei-ehn after sind then pointed out in the elnims.

A practical emlmdiment of the invention is represented in the accompanying drawings forming a part of this speciiiieution, in which similar characters of reference indicate eorresponding purts in :ill the views.

Figure l is :i cross section of the improvei ment, on the line 1 1 of Fig. 2; Fig. is :t Sectional plan view of the seme on they line 22 of Fig. 1; Fig. 3 is zi`trnnsverse section of the sume on the line 534-3 of Fig. 1 Fig. 4 isan enlarged phm view of the :iutonnxtio abutment; lig. 5 is en end view of the sume; Fig. 6 is :in enlarged sectional side elevation of the improvement; Fig. 7 is :i side elevattion ofthe rotor; Fig` S is on end view of the sume; Fig. ison enlargedseotionul side elevtion of the pecking for the rotor in the uylinder, and Fig. l() is n crows` section of the iinprovenrent showing the rotor und the, nutomntic abutment in it dill'erent position from the one shown in Figs. 1 und fi.

I'n the cylinder A of e rotary engine is mounted to turn the rotor B, secured on the. shaft C, journeled in suitable hearings l), carried by spiders E nttnched to the cylinder Ant the open ends thereof. The rotor l5 is rovided on its peripheral farce with e heed in frictioniil contact with the inner suifece of the cylinder A. 'lhe cylinder A is intersectedV fit the top by the abutment sent IF, containing im eutonuitie, oscilhtting rotor abutment Gin frictionnl contact with the pe.- riphernl'suifztce of the rotor B, to form with the hitter a working ehumlier i-n the cylinder A, with e view to turn the rotor l in cither u forwurd direction, ns indieuted hy the zurow a', or in the inverse direction thereof, :is hereinufter more fully ex lained. I'he rotor abutment G is marde ho low und consists essentially of trunnions G', journnled m the ends ol' the rotor realt l", .nd the trunnions G nre connected with euch other by :i cross piece (if, having iteci ds connected with euch other hy n rim (13, Ltliicg the peripheral iin-.e o'l' the sent F. 'lhe rim b of the hollow abutment G is provided with sets of porte ci, b and c, d, :.drpled lo register with ports e,f, l'ornied on top o1' the nett F, and controlled by n reversing stile vulve Il, urrnnged in o steam client I, coniected hy it piped with u hoilcr or other suitniile niotlre ugent supply, the seid pipe J Leng provided with a vulve J und :i try-pass Ji, es indicated in lig. 1.

The slide vulve 1I is provided with e vulve stem il', connected :it its outer end by u. link il with o. hund lever' li, under the control ol the operator, to permit the hitterto shift theslide vulve IL from the position shown in Iigs. 1 und (i to that illustrutedin dotted linee in i* ig. 'lhe slide vulve ll is provided with the ports g und l1, of which the port g is udupted to register with the portf, its shown in 1i jgs. 1 und l, while the )ort h is udupted to rcgieter with the port e wlhonever the vulve il is shifted into the reversing position indicated in dotted lilies in l* ig. t5. into the vulve ezit- F open the exhaust portsi und j, opened or closed hy the :slide vulvetli, :1nd connected with the exhaust pipes K und K', forcuriying the exhzrunt inoltre ugent to a suitable pince of nist lmrgc. Vl hen the slide vulve Il is in the position ehoun iu l1 igs. 1 und (i, the exhaust port 'i is closed while the cxlmust port i5 open, und when the vulve II is reversed then Vthe port i. is opened und the port is closed.

'l`runsveri1ely through the hollow uhut nient vulve (i extends :L iixed uhutment F', forming purt of the :thutnient sent F, to direct the stcum or other motive ugent into either side of the abutment G, to hold the lutter in n forward or reverse position, es indicated in full und dotted lines in Fig. 6.

Villen the several p atrts ere in the position shown in Figs. 1 und (i,`the ports e, h, c und 'a ure closed, while the ports b, g, d und j are open, so that the motive agent in the steam chest I eun mss by wey of the registering ports g,f:nu b into the hollow' abutment :md through the sume. :ind by wuy ofthe port d into the working chuniber of the cylinder A, to press nguiust the heed B' ofthe rotor B, to rotute che lutter in the direction of the The exhaust motive ugent in through the exarrow a. front of the head b plissee hnust )ort j und pipe h to u. suitoble pince how it will be noticed tlutt by of disc urge. having the fixed ubutnient 1* through. the rotor abutment (i, the ino e). tending two ,agent holds the rotor nbutnient (i ni the po" sitiou indicated in'bigs. 1 und 6., und idlons the snid rotor abutment to yield und ost-lliure .order to prevent the abutment t; from turning ovel` into a reversing position, u snmll port /c is provided in thel rini (111 to more iu register with the port `dur.ng the time the abutment (1 is turned y the head h of the 1G* by the pressure of the si :turn into the rotor .b to permit stennl to mss into the rotor abutment und to eounter- :thune the seine. lo hen the operator desires to reverse the ongine, he moves the hund lever 113 into the position shoun in dotted Lues in Lig. l, so that the port y is moved out of register with the port lnle the port h moves u1 register `with the port e. nt the sume time the valve 11 opens the exhaust `port 'i und closes the exhaust port ihe motive agent in the steam chest 1 now pussesqbv nay of the registering ports h, e, a into the interior of the -rotor abutment (i, nt the right hund sido of the xed abutment l, so that the abutment :un is mused to ositiou show i. in dotted lung in big. (i. VN lien this trikes pinne the port r moves into register with the port whipr the i ort a opens into the cylinder A :it the right liu'ndside of the rotor abutment (i, :uid solo lseq'uently the rotor B is now unused to rotatie 1n the reverse di reetion of the arrow a. When the rotor abutment G turns into the reverse position shown in dotted lines in l* ig. 6, then the post 'i is opened to permit the exhaust motive agent in front of the heed l5 fd pass by way of the port t' und the pipe K to a Li eee of discharge.

` Y n order to hold the abutment G in the reverse position and during,r the time the abutment VG is caused to time 'the head B' passes the abutment, sleinn is passed into the abutment by wey of n snnill o'rt k formed in the rim (i3 ol the abutment, and adapted to register with the port e when the port c is out oif during the oscillation of the abutment G by the pus-sage ut ttelgeed B u'nd u smell port l is arranged betwbertthe ports k, lc in the rim G of the abutment G to admit a small amount of motive ugent into the abutment G to uct in the sume manner when the rotor is in the reverse motion.

In order to render the ,rotor B as steinnM tight as possible in the cylinder A, the peri phernl luceolthel rotor 1s provided with nngular pecking-rines Il, made of steel or other sultab q mateia and having outwardlysligntly oseillute ut tte i )during this iuovef i i l l l l i i i l l l extending members L (see Fig. D), soili- Ciently thin to be pressed outward h v the motive ugent und in a'onlnrl` with the will of tl e reces A. formed in tiro v ."lindor, :und in wliirh lit tlflexible members ol' tlm plu-.kings li.
